Soft-clamped silicon nitride string resonators at millikelvin temperatures
Thomas Gisler, Mohamed Helal, Deividas Sabonis +5
We demonstrate that soft-clamped silicon nitride strings with large aspect ratio can be operated at \si{\milli\kelvin} temperatures. The quality factors () of two measured devic…
Strong parametric coupling between two ultra-coherent membrane modes
David Hälg, Thomas Gisler, Eric C. Langman +5
We demonstrate parametric coupling between two modes of a silicon nitride membrane. We achieve the coupling by applying an oscillating voltage to a sharp metal tip that approaches…
Spatially resolved surface dissipation over metal and dielectric substrates
Martin Héritier, Raphael Pachlatko, Ye Tao +3
We report spatially resolved measurements of static and fluctuating electric fields over conductive (Au) and non-conductive (SiO2) surfaces. Using an ultrasensitive `nanoladder' ca…
Parallel detection and spatial mapping of large nuclear spin clusters
K. S. Cujia, K. Herb, J. Zopes +2
Nuclear magnetic resonance imaging (MRI) at the atomic scale offers exciting prospects for determining the structure and function of individual molecules and proteins. Quantum defe…
Technical Review: Imaging weak magnetic field patterns on the nanometer-scale and its application to 2D materials
Estefani Marchiori, Lorenzo Ceccarelli, Nicola Rossi +3
Nanometer-scale imaging of magnetization and current density is the key to deciphering the mechanisms behind a variety of new and poorly understood condensed matter phenomena. The…
